I think it was the skill of the drivers and the preparation of the track that prevented any more flips than we saw. Never a rut anywhere in that track. Smooth as silk all the way across the track, perfect for that gutsy slide job. Cushion about 2 feet off the wall, just the right amount to use that boiler plate for a little richotchet action. Some guys fear that plate wall, so they do not show up at this track. The ones with the big kahunas play with that wall. Nuff said.
